The picture of the derailleur in this advert is very indistinct - but my guess is that this is a different design from that in Shimano’s earlier adverts. I think that the word on the outer plate is ‘Shimano’ rather than ‘Sportsman’. I also think that the distinctive point has disappeared from the bottom of the pulley cage.
It’s notable that a number of 1960s Japanese derailleur adverts feature women cycling. It’s also a truth universally acknowledged that tartan is wretchedly under used in cycle clothing.
